Mandarin Logbook

Mandarin Logbook helps high school Chinese students turn class notes into a simple study routine. Capture Mandarin words and phrases with pinyin, English meanings, example sentences, class notes, tags, and mastery status. Build a focused practice deck, review progress insights, and use optional daily reminders to return to important vocabulary. The app is for study organization, not translation certification or classroom grading. Mandarin Logbook works offline and stores study notes on the device. It requests notification permission for optional daily review reminders and boot completed access to restore local reminders after restart. The tested APK did not request Internet, location, camera, microphone, contacts, SMS, phone, storage, accessibility, VPN, or overlay permissions.
